  • Device for testing material and measuring thickness on a test object having at least electrically conducting and ferromagnetic material parts
    Patent number: 8079266
    Abstract: A device is disclosed for material testing on a test object having at least electrically conducting and ferromagnetic material parts. The test object has at least one technical surface on which at least one electromagnetic ultrasonic transducer (EMUS) is rolled. The at least one transducer includes at least one permanent magnet or an electromagnet and at least one eddy current coil. The at least one eddy current coil has at least one electrical strip conductor which is disposed at or parallel to a surface area of a rolling member which can be rolled on the technical surface of the test object, with the surface area rolling along with the rolling member during rolling.
